Turok evolution would be up there (so would Timesplitters 2) if this was ONLY about multiplayer. But it is not.
Turok evolution has MAJOR issues with story progression. Half the time you are wondering "Why am I seeking this objective?"

NONE. I hate First Person 'Shooters' Doom was kind of cool during the time, and Golden Eye 007 used to fun on Multiplayer back on the N64, but now it just leaves an ultra bitter taste in my mouth. Metroid Prime 1-3 however are First Person ADVENTURE Godly they are Obiwan. k

Discounting the Prime games (which I see as first person adventure games), my favourite by far is 007 Nightfire. The single player was OK, but the multiplayer was fantastic. I don't even like FPS games that much, but this game was amazing, even better than Goldeneye in my opinion (I apologize for my blasphemy)

Phoenix Base, King of the Hill, State of the Art weapons. Pure chaotic fun.
